Feb. 16 (UPI) --University of Maryland researchers designed "Smart Underwear" to track and measure flatulence -- and they are seeking volunteers to wear them. Brantley Hall, an assistant professor in ...

Scientists at the University of Maryland have created Smart Underwear, the first wearable device designed to measure human flatulence. By tracking hydrogen in flatus, the device helps scientists ...

Abstract: A hydrogen gas sensor based on peak-delay measurement of ultrasonic time-of-flight (TOF) is reported. The sensor integrates a time-to-digital converter (TDC), a pair of 200 kHz ultrasonic ...

Quantum sensors are transforming how we measure and navigate, offering levels of precision far beyond classical systems. By exploiting atomic superposition, cold atom interferometers, and diamond NV ...

A new technology has been developed that enables cuffless non-invasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional ...

PCWorld explains how to create an affordable CO2 air quality monitor using a Raspberry Pi and MH-Z19C sensor for under $40. This DIY project helps monitor indoor air quality since high CO2 levels ...

Abstract: Here a microwave sensor for non-invasive blood glucose measurement is proposed. To achieve a high sensitivity, this sensor uses a complementary electric-LC resonator with strong ...

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...

CU Boulder Today—A team of University of Colorado Boulder researchers is making reliable, inexpensive and easy-to-deploy sensors that monitor soil in real time as it, essentially, breathes in and out.
